Product information "JUMO wall resistance thermometer with remote protection tube Protection class IP65 "
Wall-Mounted Resistance Thermometer by JUMO with Pt100 and Integrated Transmitter with 4–20 mA and Measuring Range -40 to +80 °C
JUMO Wall-Mounted Resistance Thermometer with Remote Protection Tube Protection Class IP65 Type: 902520/23-474-1003-1/330,(-40..80°C)
The wall-mounted resistance thermometer is suitable for HVAC temperature measurements with direct analog signal transmission. Equipped with Pt100 in a two-wire circuit, an integrated 4 to 20 mA transmitter, and a measuring range of -40 to +80 °C, this version is particularly suitable for robust wall-mounted measuring points with a separated measuring location.
This version is designed for wall-mounted measuring points where the temperature value should be recorded at a location slightly removed from the housing and transmitted directly as a current signal. For this purpose, the version is equipped with a remote protection tube.
Technical Data
- Version: Wall-mounted resistance thermometer with remote protection tube
- Measuring insert: 1 x Pt100
- Circuit type: Two-wire circuit
- Transmitter: 1 x analog, output 4 to 20 mA
- Measuring range: -40 to +80 °C
- Note: Measuring range only in combination with transmitter
- Protection class: IP65
Advantages and Technical Features of this Wall-Mounted Resistance Thermometer
- remote protection tube for more targeted temperature measurement
- well suited for wall-mounted measuring points with a separated measuring location
- no additional external signal conversion required
- suitable for applications with an extended temperature range up to +80 °C
The remote protection tube offers a clear advantage: the sensor can be positioned closer to the actual measuring point while the housing remains mounted separately on the wall. This is practical wherever temperature values should not be measured directly at the housing position but require a small distance from the actual measuring location.
In addition, the integrated 4 to 20 mA transmitter provides the temperature signal immediately as a common analog output signal and allows direct connection to suitable controllers or control systems. Especially in building automation and HVAC applications, this is useful when no additional external signal conversion is planned. The associated measuring range is -40 to +80 °C and applies to this version in combination with the transmitter.
The housing design is also intended for more demanding installation environments. With protection class IP65, the device is well protected against dust and water. This makes the version particularly suitable for wall-mounted measuring points in technically demanding indoor areas or protected outdoor areas.
Typical Applications
- Wall-mounted measuring points in HVAC applications
- Building automation
- Heating, ventilation, and air conditioning systems
- Measuring points with a slightly remote measuring location
- Technical indoor areas and protected outdoor areas
